如何通过ILGenerator.Emit*调用“normal”方法？

Question

DynamicMethod是否可以调用(例如，通过ILGenerator.EmitCall或类似的)“正常”方法，例如私有子对象(ByVal obj as Object)？

提前感谢

Answer 1

delegate void foo();

public static void show(string foo)
{
    MessageBox.Show(foo);
}

public void test()
{
    DynamicMethod dm = new DynamicMethod("foo", null, null);
    ILGenerator gen = dm.GetILGenerator();
    gen.Emit(OpCodes.Ldstr, "hello world");
    gen.EmitCall(OpCodes.Call, this.GetType().GetMethod("show"),null);
    gen.Emit(OpCodes.Ret);
    var b = dm.CreateDelegate(typeof(foo)) as foo;
    b();
}

Answer 2

将赋值给该方法的计算堆栈上的加载值

MethodInfo methodInfo = typeof(ClassName).GetMethod(MethodName, new Type[1] { typeof(-method argument types-) });

IL.Emit(OpCodes.Call, methodInfo );
